The invention relatesto a valve construe,y tion and 'more' especiallyto automatically operatedl valve mechanisms Vfor flush tanks.

The primary object of the invention is the provision of mechanismV of this character wherein bothl the inlet and outlet valves of the flush tank will be automatically con-v trolled and inthe construction eliminates the usual fault of the various types of stand-v ard valves operative within the water in the flush tank as these corrode, the mechanism performing the dual function to control the intake and also the outlet to and from the tank.

Another object of the invention is the provision of mechanism of this character, wherein the construction thereof is novel in form and the controlling element being disposed outside of the flush tank and in the operation thereof automatically regulates the intake of water to the tank on the opera tion of the outlet valve for discharge of water from the tank.

A further object of the invention is the provision of mechanism of this character which is comparatively simple in construction, thoroughly reliable and efficient in its purpose, readily and easily accessible and susceptible of adjustment for the automatic working thereof and also inexpensive to manufacture and install.

With these and other objects in view, the

invention consists in the features of construction, combination and arrangement of part-s as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawings Figure l is a top planview of the flush tank showing the intake and outlet with the mechanism constructed in accordance with the invention installed.

Figure 2 is a front elevation.

Figure 3 is an enlarged fragmentary elevation of the mechanism, a part thereof being in section.

Figure 4 is a fragmentary detail plan view.

Referring to the drawings in detail, A'

designates a Hush tankof standard `type or designV having associated therewith the water inlet pipe l0 and water outlet pipe l1, the, latter bein extended toa `toilet bowl (not shown) for Hthe .flushingthereof in the usual well known manner. u

The outlet pipe 1l leading from the tank A is normally closed by a lift valve 12 and is operated from a rotatable vhandpiece 13, the same being located outside of the front ofthe `tank A `:and has journaled infits front wall the turning shaft 14 of which being disposedtransversely of the tank and suitably journaled in both the front 'and back walls thereof.- This shaft 14 carries acam projection '515, which operates -upon a crank 16., the latter being connected'fthrough the mediumrof the link 17 with theli-ft valve 12 softhat Vupon rotation' ofthe hand piece 13 the valve 12 will be lifted from its seat for'the Aopening of the outlet pipe 11- to permit the water within the tank to `iushv a toilet-bowl.

-The intake pipe I() which ported adjacent to lthe intake pipe 10 close tothe valve casing-18 is a=cy-linder23 in which worksfa piston 24 on'a stem or rod 25 sli'dablevthroughia collar26 adjustably mounted in the 'upper end 27 lor head for thecylinder T23 and. thisfstem Vor rlod has pivoted thereto ias at 28 .the lever-22 so that on upward movement of `theisteim or rod 25 the ,plug valve 19 will be rotated through the instrumentality ofthe lever'22 for :the

y opens, into lthe tank A for supplying water thereto has -aropening of the valve in the intake pipe 10 to permit the filling of the tank A and upon downward movement of said stem or rod 25 the plug valve 19 will be closed.

Mounted upon the support for the tank A next to its rear wall isa rocker 28, the end 29 of which being engagedby a nut 30 adjustably fitted on the upper free end of the stem or rod 25 whilev the opposite end 31 plays against the cam"32"'onthe shaft,`

14 of the hand piece 13 and this cam 32 being located over the rocker 28 and outside of the tank A. Thus it will bev seen that when the hand piece-13 is swung in one direction the cam 32 will impart movement to the rocker 28 Vwhereby the stem or rod 25 willbe 'lifted and-in this manner the plug valve 19 opened in the vcasing 18. in the intake pipe '10 for the filling of the flush tank A as willr ybe obvious. Y

Coiled about the stemor rod 25 within the cylinder 23,is a coiled expansion spring 33, one end bearing against the piston 24 `while its opposite endv is seated against an fes;

annular ange 34 onthe inner end of the collar 26, which latter is adjustable in the end4 or head 27 of thecylinder 23 to vary the tension of the spring 33 which is active upon the piston 24 to llower the same within the cylinder 23 upon the'V lifting or upward movement of said stem or rod-25 and this spring functions to automatically close-the plug valve 19. in the valve casing 18.--

The end .or head 27 of the cylinder 23 is formed, with suitable apertures -35 to permit the;escapement of air from the cylinder 23 upon upward` movement of the piston 24 therein. The ,piston 24 `is provided with suitable packings 36 sojas to prevent the possibility of air passing from Vthe-upper sideA of the rcylinder 23 kto the lower side thereof relative to the piston 24 therein. .Y It will be apparentithat when the hand piece 13 is operated tolit the, valve l2 the plug valve 19 will be. simultaneously operated for the j opening of .the intake to the tank A and-the quantity lof water admitted to the tank A from the intake pipe 1() ,is determined by the time it takes the `f pistoIL24A to finish its downward movement in thejcylinder v.23`under the action of the spring 33 upon this piston. w Itvwill also be observed thaty the mechanism for controlling: the intake valve 19 is located outside of the tank so -that corrosion of such mechanism is eliminated as the same will not be subjected to water. which would be the case if located within the tank A.

Fitted inthe bottom of the cylinder 23 isv an adjusting screw 37 which controls a plurality of escapement ports 38 in the bottom. of said cylinder whereby, the speed of downward Amovement of theypiston 24 in itsaction can be determined'as the escape# ment of; air from betweenfsaid piston and turn lever connected withthe -valve ofthevwaterinlet VWith ysliding connection there? between, va cylinder having a removable head anda Vented end opposite thereto, a vent control screw operating with respect to said; vent,y a: piston within the cylinder and having a stem passed through its removable head, arfollower plate adjustably engaged in'therremovable head, a coiledl o tensioningv spring between the plate and piston, a pivot connection between the lever and lsaid stem, a rocker operable by thecam of said first named lever andstr'addling thel same, and a half-spherical nut adjustably engaging the stem andA forming a fulcrum for the straddling lever. f c v In testimony whereof I aiiix my signature.
